DracoBlue I also had this issue, and it was resolved with Adam's help. It turned out that CPGuard cron jobs were causing OpenLiteSpeed to restart. I reported it to CPGuard as well, and they confirmed that the issue has been resolved.
DracoBlue How's the situation on your end? My OLS hasn't restarted for 18 hours, so Adam's assumption that the issue was caused by CPGuard's cron jobs was correct (Adam Master). CPGuard also released a fix, and everything is running smoothly.
btraill I received an alert last night... I can see that cpFence also just released their update to mitigate this. Hopefully I don't see it again!
